Sketch the plane curve in the xy-plane and find its length over the given interval:
r(t) = (6t-3)i + (8t+1)j on [0,3]
Here's what I've got so far:
r'(t) = 6i + 8j
llr'(t)ll = sqrt of 6^2+8^2 = 10
s = integral 0-3 10dt
= 10x ]0 to 3
= [30-0]
= 30I just need help on how to sketch this plane curve. Thanks.
